Genes affected

GLT6D1 (HGNC:23671): (glycosyltransferase 6 domain containing 1) The GT6 glycosyltransferases gene family, which includes the ABO blood group (ABO; MIM 110300) and GLT6D1, shows a complex evolution pattern, with multiple events of gain and loss in different mammal species. In humans, the ABO gene is considered the sole functional member, although the O allele is null and is fixed in certain populations (summary by Casals et al. (2009) [PubMed 19218399]).[supplied by OMIM, Jan 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.3 is higher than 0.05.
